Fig. 6 is a longitudinal section showing the arrangement for operating an auger-drill, Fig. 3 showing the arrangement for operating the rock-drill. Fig. 7 is an enlarged detail showing the manner of constructing the auger-flight. Figs. 8 and 9 are details showing the lock for the auger to the drill-rod. Figs. l0 and ll are details showing the locking and releasing' device for the winding-drum of the rope for the auger. Fig. l2 is a detail showing the grip for the drillrod, to which the lifting-rope is attached. Fig. 13 is a detail showing the device for locking the drill-rod to the derrick. Fig. 14: is a detail in section, showing the head carrying the derrick and to which the power is applied. Fig. l5 is a detail, being a top or plan View of the device for operating the drill.

This invention has for its objects to mprove well-boring machinery iu respect to the means employed for giving the drill-rod a rotary motion and the means used for raising a dirt-carrying auger to clear the hole as fast as bored, irrespective of the depth of the well or hole, and operating a rock-drill, and also to improve in this class of machines the several parts and their arrangement to produce the best results in use in reference to the construction and operation of the machine as a whole; and its nature consists in the several parts and combination of parts hereinafter described, and pointed out in the claims as new.

In the drawings, A represents the front wheels, mounted on an axle A.

B are the rear wheels, mounted on an axle B.

O are the side pieces of the front section of the frame, connected at the front end by a cross-piece, and having secured near their inner ends a cross-piece C. The side pieces C rest upon a bolster connected to the axle A by a king-bolt to allow the front wheels A to turn.

D are the side pieces ot the rear sect-ion of the frame, connected at their rear end by a cross-piece, and having secured to theirinner ends a cross-piece D', from each end ot' which depends a bracket D2.

E is an arch formed of four uprights, of angle-iron, each upright having at its lower end a base or leg portion E', with a fiange which can be bolted to the respective side pieces O D and complete the frame. The corner pieces or uprights of the arch E stand inclined, and at the upper end of each side a flange E2 is formed.

F is a cylinder having at its lower end a ange or rim F', through which and the iianges E2 bolts ct are passed for securing the cylinder F rmly to the arch E.

G is an inner cylinder within the cylinder F and having at its upper enda rim or ange G, the periphery of which is formed with a gear o.

H is an exterior cylinder surrounding the cylinder F between the anges F and G', and having at its lower end a ange II', the periphery olf-which is formed with a bevelgear c. The cylinder F forms a bearing for both of the cylinders G and H, and, as shown in Fig. 6, across the inner cylinder is a crosspiece G2, having a central hole which forms a guide for and prevents wabbling of the drill-rod.

I is a sweep, the inner end of which is secured in a socket I on a band I2, which band encircles the cylinder II at its upper end andis firmly secured to the cylinder by a clamping-bolt, so that the movement of the sweep will rotate the cylinder II. The socket I' has a second socket d, in which is a sliding latch c, the outer end of which is made to engage with the gear b and lock the sweep to the cylinder Gfor rotating such cylinder, and, as shown, the latch e is connected by a rod e with an L-shaped lever e2, pivotally supported by ears e3 on the sweep I, so that the operator by movin g the L-lever can lock the sweep IOO to Or unlock it from the cylinder G, and, as shown, in order to support the sweep, bracerods e4 are provided running from the socket I' to the encircling bands l2 on each side.

J are the corner posts or uprights of the derrick, the lower end of each post being firmly secured by bolts or otherwise to the inner cylinder G, and, as shown, the posts J are braced by cross-pieces J', and to their upper ends is secured a cap or top plate J2, having a central hole.

K is the drill-rod, thelower section of which at its lower end carries a drill-point K', and at the lower end of the rod on opposite sides is a flange or key t', firmly secured to the rod. A gripper or holder K2 is mounted on the drill-rod above the auger, as shown in Fig. 1. This gripper is formed, as shown iu Fig. 12, of a disk or plate g, having an annular flange or ring g' and a plate or disk g2, which plate and the plate g have a central annular hole g3, and between the plates g and g2, inside of the ange g', is a ring h, having a triangular shape in cross-section to present a sharp edge for engagement with the drill-rod, and between the plates g and g2, outside of the ring g', is a ring h', having on one side an extension h2 for the attachment of a rope or cable. This gripper or holder operates by lifting on the extension h2, which forces the edge of the ring ZL into the drill-rod, the hole g2 allowing sufficient play of the gripper for this purpose.

L is the tube or center of the auger, of an interior diameter to fit around the drill-rod so as to slide thereon. The flight for the auger is formed of a rst section L', which is bolted to a'bracket k, which bracket is bolted or riveted to the tube or center L, and the balance of the flight is made up of sections L2, each section at its end, as shown, being partially cut away to form overlapping ends k', which are secured together by bolts; but the ends may be secured together without being cut away. This manner of forming the Hight enables the flight to be readily constructed in sections and the sections united one to the other so as to 'be firm around the center or tube and havethe necessary strength to withstand the strain in use, making as strong a flight as one made of a continuous strip without the expenditure of the time and labor required in making a flight from a continuous strip. At the top end of the iiight is another bracket similar to the bracket (not shown) which is bolted or riveted to the tube L, and to which the upper end of the flight is fastened.

On the center of tube L, above the flight, is securedy a support L2, formed by securing two rings j to the tube or center, with an intermediate ring j between them, which ring has pivots t7'2 on opposite sides, to which is pivoted the open end of a bail or yoke ja for the attachment of a rope, by which theauger is raised and lowered.

M isa cross-head located between the posts J, and ha ving at each end a wheel or roller M' to rnnbetween the posts, as shown in Fig. 13. This cross-head at its center is enlarged and has a circular hole through which the drill-rod K can pass, and on one side of this cross-head in a recess f' is located a wedge f, having a tooth or serrated edge for engagement with the drill-rod, and this wedge, as shown, is forced into engagement with the rod by set-bolts f2, and when locked against the rod the rod is locked to the cross-head, which is rotated by the derrick and the cylinder G.

N is a rope or cable, one end of which is attached to the gripper or holder K2, and the other end is attached to a winding-drum around which the rope is coiled.

O is the winding-drum, which has at one end a disk or plate O' and at the other end a gear-wheel P' and is mounted 011 a shaft O2.

Pis a gear-wheel meshing with the gearwheel P' for turning the drum O.

Q is a shaft on which is secured the gear P. This shaft at one end has secured thereto a crank or handle Q', by which the shaft is turned, and the shaft is mounted in suitable boxes Q2 ou the side pieces C, and, as shown, the shaft O2 is supported at the ends in the base E'.

On the shaft Q, adjacent to the handle Q', is a ratchet-wheel m, which is engaged by a spring ratchet or pawl m', by which the shaft Q is locked against backward rotation except when the pawl is released from engagement.

,The rope N is attached to the extension h2 of the gripper K2 and passes up and over a pulley-wheel Z, supported ina stirrup Z', suspended from a shaft Z2, running across the arch E at its upper end, and this rope, in connection with the drum O and its driving devices, operates to raise the drill-rod by drawing up on the gripper K2 to force the ring h into.

bite or engagement with the drill-rod, so as to elevate the rod by winding up the rope.

R is a rope or cable, one end of which is fastened to the bailj3 of the support L3 and the other end is attached to a drum on which the rope is wound.

S is the winding-drum for the rope R, which passes over a pulley n, mounted in a stirrup n', suspended from a rod n2, running across the arch E. The drum S has at one end a disk S' and at the opposite end a disk S2, and on this disk S2 is formed or secured a ratchet or toothed wheel o, with which a sliding latch .0', located between guides 02 on the side piece D, can be made to engage, and,as shown, the sliding latch o is thrown into or out of engagement by a lever p, supported on a standard p by a suitableVV pin or pivot, so that by moving the lever the latch o' can be operated. The drum S can be stopped when the latch o' is out of engagement by the brake-block q, carried by the lever q', which lever is lockedl by a sliding latch with a rack q2. This brakeblock q can be forced against the rim of the disk S2 with sufficient force to stop the rota- IOS IIO

IISYY tion of the drum, or its pressure can be such as to grade the speed at which the drum runs when released from its driving-clutch.

T is the shaft on which the drum S is mounted, so as to run free and have an end- Wise movement for engagement with its driving-clutch, one section of which is carried by a sleeve T on the shaft T. The drum Sis moved endwise bya rockshaft r, having an arm or lever Ir and mounted in boxes r2 on the side piece D of the frame, and this shaft fr has a short arm s, to which is connected one end of a rod s,the other end of which is connected to a ring, as usual, locatedin a groove in the hub of the disk S2, by which means the reel is free to turn on the shaft T, and at the same time can be moved inward to cause the clutch-section t on the disk S te engage with the clutch-section t on the collar T to cause the clutch to drive the reel in the direction to wind the rope R thereon, and by moving the reel backward the clutch-sections t t will be disengaged, allowing the reel to run back ward loosely and unwind the rope therefrom, and the speed of the reel in unwinding can be regulated by the brake-block q, or by this brake-block the unwinding can be stopped. The sleeve T with its clutch-section t, is driven by a bevel-gear 't2 on the collar T, which meshes with a bevel-gear u2 on a rod u, which rod runs up at one corner of the arch and at its upper end is supported in a box U3, attached to the arch, and to the upper end of the rod or shaft u is secured a bevel-gear u, which meshes with the bevelgear c on the flange H of the cylinder H, so that the rotation of the cylinder will, through the gears c and u', rotate the rod u.

U is a wheel or disk having on its periphery a series of projections U and mounted on a shaft U2, journaled at its ends in the brackets D2.

V are bars attached to the axle B by bolts or otherwise and located to have one bar on each side of the wheel or disk U, and each bar at its outer end has a head V, on which is an incline '03. Each bar V, at the point where the shaft U2 passes, is provided with an ear fu, adjacent to which on the shaft is a collar n', which is locked to the shaft by a set-screw or bolt r2, by which means the bars are locked against side movement or spring.

XV are bars, one on each side of the wheel U, and pivotally connected to the hub of the wheel or to the shaft U2 between the wheel and the ear n. Each bar has a slit w, in which is located the end of a pin or pivot tu, to which is secured a sliding stop XV which Stop is of greater width than the space between the bars XV, allowing the edges to2 to rest on top of the bars. At each end of the pin or pivot w is mounted an anti-friction roller w3, which runs on the incline v2 as the bars XV are forced down by the engagement of the sliding stop XV with a projection U', which engagement is had by the rotation of the wheel U, which carries the projections U around successively to engage with the stop XV when the bars XV are elevated, as shown in Fig. 8, and cause such engagement to carry the bars down with the continued rotation ot' the wheel U, as shown in Fig. t. The stop XV is drawn back and released from engagement with the projection or cam U by the travel of the anti-friction rollers '1,02 down the inclines r2 of the heads V', and as soon as the stop is released from engagement the bars XV are elevated by the weight of the drill, and in being elevated the stop is returned as soon as released by the action of a push-spring 104, secured to the bars XV and the stop XV, as shown in Fig. (j, and such return brings the stop in position to be ein gaged by the next succeeding projection U, and this forward-and-back movement of the stop is permitted by the slot w.

X is a walking-beam pivotally attached at its inner end toa bracket C2 on the crosspiece C and connected at it-s free end with the free end of the bars XV by a link and this walking-beam has a pulley y connected therewith by a stirrup or hanger y Y is a pulley mounted between ears or brackets Y on the cap or top plate J 2, and over which a rope R runs when the machine is used for operating a rock-drill, and when operating a rock-drill the parts U, V, XV, and X. and the devices connected therewith are brought into play; but when operating an auger these parts are thrown out of use and a drill-rod with anauger thereon is substituted, as shown in Fig. l, Fig. 6 showing the drill-operating devices.

Z is a drive-chain running over asprocketwheel ,e en the end of the shaft T and a sprocket-wheel z on the end of the shaft U2, and by which the shaft U2 is driven from the shaft T to drive the wheel U.

The machine for use with a drill and auger is arranged as shown in Fig. l, in which arrangement the auger is slid onto the drill-rod K and the drill--rod passed up through the arch and cylinders and guide or cross head M to the top of the derrick, successive sections of the drill-rod being added as the drill descends. The auger is locked to the drillrod to be rotated therewith by the engagement of the keys i with the slots or recesses z" in the tube L, and the rotation of the drill-rod and auger is had by the rotation of the derrick K and cross-head M from the cylinder Gr, as already described. The auger when full is raised by means of the rope R, which rope is wound onto the drum S by throwing the drum into engagement with the collar T', and when the au ger is raised above the surface it is unloaded and the drum released from its clutch, allowing the rope to unwind and the auger to descend on the drillrod K to be again operated, illed, and raised, and these movements will continue until the hole is finished, or unt-il a rock stratum or other hard material which requires the employment of a rockdrill is reached. The drill-rod descends by IOO gravity, and when required to be raised the gripper K2 is made to bite onto the rod by drawing on the rope N, and the rope is then wound onto the drum O by turning the shaft Q through the crank Q', which, through the gear-wheelsP and P', drives the dru rn to wind the rope thereon.

The machine for use with a rock-drill is arranged as shown in Fig. 3, and when so arranged the drill-rod K, with its auger, is removed and the rope R is attached to the eye of the rod of the rock-drill, and thence runs up through the cylinders and derrick and over the pulley and down under the pulleyy across to the drum S, and the walking-beam X is connected with the trip mechanism by a link and bars W. The bars W are thrown down by the action of the wheel U, as already described, and such downward movement of the bars Wwill carry down the walking-beaxn.X, drawing the rope R up and raising the drill, and the drill will be raised until the stop W is released from its engagement, which allows Jthe bars W and Walking-beam to rise and the drill to drop and perform its Work. The drum YS is left unclutched and is locked in position by the latch 0', and when more rope is required the latch is released, allowing the rope to unwind, and in unwinding the brakeblock q can be brought into use to regulate the speed or stop the unwinding, and when itis desired to raise the drill out ot the ground or to a greater distance than the action of the walkingbeam would raise it the drum-clutch is brought into engagement and the rope R Wound onto the drum to the extent required.

What I claim as new, and desire to secure by Letters Patent, is-

l. The combination of a rotating disk or wheel provided with projections With bars WV, a sliding spring-catch mounted on said bars, inclines o3, and a walking-beam connected with the rope of a drill-rod, substantially asand for the purpose specified.

2. The Wheel U, having projections U, bars W, having inclines e3, and sliding stop NV', having a spring w, in combination with a walking-beam X, rope R, and pulleys Yy, substantially as and for the purpose specified.
